Makita 19 Piece HSS TiN Metal Drill Bit Set - Makita - D-67527

These drill bits are primarily designed for use on alloyed and non-alloyed steel. While they may work on other metals, their performance is optimized for steel.

Select the drill bit size that matches the size requirements of the screws or fasteners you'll be using. Measure the outer diameter of the screw and choose the appropriate size.

Clean the bits after each use, store them in a dry place, and consider using cutting oil when drilling into hard metals to reduce friction and heat.

The titanium-nitride coating reduces friction, heat buildup, and wear, leading to cleaner holes and extended bit life.

HSS (High-Speed Steel) construction ensures the drill bits are durable and suitable for drilling into alloyed and non-alloyed steel.

Store the drill bit set in its carrying case in a dry place. This protects the bits from rust and keeps them organized.

Yes, these bits are compatible with both handheld drills and drill presses.

Check if the drill bit is worn. Replace with a new drill bit from the set or sharpen the current bit using a drill bit sharpener.

Ensure you are using the split point bit, and apply appropriate pressure. If using a standard bit, use a center punch to create a pilot hole before drilling.

Reduce the drilling speed, apply cutting oil, and allow the drill bit to cool down periodically.

Ensure you are applying even pressure, are using the correct speed for the material, and that the drill bit is the correct size for the material being drilled.
